From snog-loving aliens to nightmare-envoking illusionists and father/son singing duos, the show certainly contained a great deal to talk about.

But nothing quite got the attention of the audience like Amanda Holden's plunging neckline, as she danced and smiled along with the other judges.

Amanda was wearing a white jacket and matching white tulle skirt, but the jacket left little to the imagination as it showed off her enviable cleavage.

During the filming of the auditions judging pal Alesha Dixon was caught having a sneaky peek at her friend's ample assets, while she herself was wearing just a bra under a large, electric blue coat.

Amanda, 46, is known o the show for attracting a great deal of opinions about her outfits, as one of her racier numbers landed her in hot water when broadcasting regulator Ofcom received 663 complaints for a cleavage-baring dress she wore for one of the live shows.

Despite the controversy Amanda shows no sign of changing her wardrobe any time soon as she previously joked: "Will people be complaining to Ofcom? I hope so. I really do.

"I haven't done my job if they aren't."

And tonight may have a similar effect as that live show outfit, as fans took to social media to give their sartorial judgements.
